Guys, Thanks for the feedback and for continued support of static 
linking. I will file the bug reports.

in short static linking is essential for reasonable performance of
parallel applications on Cray systems. In this scenario the application
is duplicated across 100s/1000s of compute nodes which share a
remote-parallel file system (Lustre/GPFS). As a dynamically linked
application starts, shared library loading hit's the file system hard.
However, Cray suggests users run static linked executables. Their
application launcher bypasses the file system and copies statically
linked executable directly into a ram fs onto the set of compute nodes
that a given job is scheduled to run on. This avoids file system
contention that would be introduced by a parallel application's shared
library loading.

I maintain and support ParaView and interactive OpenGL based rendering
application on NERSC's Crays. Given that this is an interactive
application, having a reasonable startup time is important. Users have
complained and I've observed times when using shared libraries when app
startup takes more than 30 min! if we build fully static executable
startup time is reduced to seconds.

For me statically linked mesa is important, which is why I want to
report this. Without OSMesa we can't use these systems, and the new
llvmpipe OSMesa state tracker has been really awesome, allowing us 
to do

things we couldn't in the past without GPUs. I hope that you don't
discontinue static link support.


Had some additional patches that cleans up mesa's build a bit further
but I guess I'll bring back (classic and gallium) static osmesa first.
Especially considering the numbers you've quoted.


We have experienced some segfaults in llvmpipe OSMesa in the static
linked version (bt shows SEGV at
create_jit_texture_type.isra.1@draw_llvm.c:128). If I can reproduce 
this

off the Cray I will file a bug report. Thought I'd mention in case you
can confirm that there is a known issue with the static link.


AFAIK static linking with llvm is a bit of a hit and miss. For that
reason mesa 10.2 may be building against shared llvm. Then again I do
not work on that part of mesa, so take this with a pinch of salt.

Brian Paul is the only person that I've seen working/bug fixing osmesa
so I'm guessing that he'll take a look in due time. Meanwhile it may be
worth filing bug report(s) for these two boogers :-)


Yes, please file bugs with as much info as possible.  I don't think I 
can help with the static build issue (my autocon/make knowledge is 
pretty thin).  I'd be happy to look into the LLVM segfault though 
(when I have time).

Hi All,


Hi Burlen


When I make a static build of mesa with osmesa+llvm, all of the llvm
related symbols are undefined in the resulting libOSMesa.a archive.
There is an "la" file produced that lists the dependencies, however
shouldn't those all be linked into the installed archive? for reference
see my configure line below.

Earlier today I have pushed a patch [1] for mesa that completely 
disabled static building for all of mesa.


While that may not be the reason for the problem you're seeing (afaics 
you're using mesa 10.1.0 and my patch just made it into master) it 
would be great if you can let us know what the your use case of 
static  OSMesa is, so that we can evaluate the situation.



Many thanks
Emil

P.S. With the commit [1] --enable-static --disable-shared will produce 
an warning message and will fall back to --disable-static 
--enable-shared.

apitrace crashes hard with OSMesa. Works fine when I use my ATI

I learned from the apitrace mailing list apitrace is currently

OK, by git bisect I've noticed that this isn't a regression in between 
9.2 and 9.2.2! The problem is because in my latest dashboard builds I'm 
using


   --with-osmesa-bits=32

which is how I usually deploy osmesa because we zbuffer precision issues 
in the past. Removing this option this tests all pass again.


Unfortunately I don't know how long this option has been a problem since 
the few VTK dashboards that test Mesa have never as far as I know built 
withh 32 bits. :-(

Re: [Mesa-dev] Mesa 9.2 release candidate 1

2013-08-20 Thread burlen

Hi Ian and All,

I tested the release candidate's llvmpipe OS Mesa on VTK's regression 
suite. it did fairly well 99% pass, however there are some regressions 
and segv's compared to OS Mesa in 9.1.5, which passes 100%. (data below)


There's a volunteer who graciously runs nightly regression suite nightly 
against various Mesa builds and makes these dashboards public[1]. Here's 
the list of failed tests for last night's OS Mesa run (on 2.1 Mesa 
9.3.0-devel (git-ff3cb37)) , 
http://open.cdash.org/viewTest.php?onlyfailed&buildid=3003558. visit the 
above link, if you click on red "failed" links, you can see an image 
diff, or in the case of tests failed with status "OTHER_FAULT" a stack 
trace. How nice is that?


Have you considered using VTK for pre-release validation? I'd never 
suggest that it be your only validation, for one thing it's only using 
OpenGL 2.1 + common extensions, so it won't give anywhere near complete 
coverage of Open GL. But, the nice thing about VTK is the level of 
testing that it goes through. Because of this it could be used as a 
reference by comparing regression test results using Mesa against those 
attained with recent NVIDIA hardware + drivers, which provide 100% 
coverage in VTK and 100% of the tests pass, or even between various Mesa 
renderers as some are less buggy than others. it's quite easy to set up 
and run and the web interface is very helpful for examining the results 
displaying image diffs etc.


btw, historically VTK has only used OpenGL 1.1 features with OS Mesa. In 
VTK master branch VTK will now take advantage of whatever Open GL 
features Mesa provides with OS Mesa. We've also made an attempt to visit 
any features that were specifically disabled because of bugs in Mesa. 
We've added a build flag VTK_IGNORE_GLDRIVER_BUGS that will enable all 
such features for validation of new Mesa releases. If you're curious 
about which Mesa was used in a given VTK dashboard submission look at 
the output of the LoadOpenGLExtension test it prints out OpenGL's 
vendor, version, renderer strings.


Thanks for all the great work, I'm looking forward to the 9.2.0 release.
